Islamic art encompasses visual arts produced from the seventh century onwards by culturally Islamic populations. An adherent of Islam is called a Muslim. Its essential religious concepts and practices include the five pillars of Islam, which are basic concepts and obligatory acts of worship, and the following of Islamic law, which touches on every aspect of life and society. The five pillars are:. Islamic art encompasses the visual arts produced from the seventh century onward by both Muslims and non-Muslims who lived within the territory that was inhabited by, or ruled by, culturally Islamic populations. It is thus a very difficult art to define because it spans some years, covering many lands and populations. This art is also not of a specific religion, time, place, or single medium. Instead Islamic art covers a range of artistic fields including architecture, calligraphy, painting, glass, ceramics, and textiles, among others. Islamic art is not restricted to religious art, but instead includes all of the art of the rich and varied cultures of Islamic societies.

This collection contains the abstracts of the papers presented in the session entitled “Illuminated Communities: The Role of the Hearth at the Beginning of Andean Civilization,” at the 84th annual meeting of the Society for American Archaeology. Hearths, often the center of a home, reveal where people gathered, what they consumed, and what they valued.
In many early Andean societies, hearths were also focal points of public ritual, placing them at the center of both family and community life during the first several millennia of social and political complexity. This session broadly explores and compares the role that hearths—whether functioning as ceremonial, domestic, or straddling the line between the two—played in the lives of people dwelling in the Andes between the Middle Preceramic and Initial Periods BC— BC.
It specifically emphasizes the creation, use, and social meanings of hearths during this period, including but also beyond the well-known Kotosh Religious Tradition. Through this focus on the hearth as both a socio-spatial anchor of ancient activity and the principle unit of our analysis, the session aims to create a dialogue between scholars working across the Andes, and in so doing, reevaluate the role of the hearth at the dawn of Andean civilization.
Hearths from over 50 domestic structures at the stratified Middle Archaic fishing villages of Paloma, Chilca Valley, Peru, were found within circles of house poles. Domestic structures were burned and abandoned, sometimes with an old male burned on top. Burials in the last occupation were placed with In this presentation, the historical processes of the Formative Period in the Ecuadorian Andes are evaluated through the material renderings of fire from the site Potrero Mendieta.
In this context, they are associated with a swift restructuring in the use of the circular architectural structures

Sexual violence is shockingly common in our society. In some Asian, African, and Middle Eastern countries, that figure is even higher. Regardless of age or gender, the impact of sexual violence goes far beyond any physical injuries. The trauma of being raped or sexually assaulted can be shattering, leaving you feeling scared, ashamed, and alone or plagued by nightmares, flashbacks, and other unpleasant memories.
You no longer trust others. You may question your judgment, your self-worth, and even your sanity. And on top of that, like many rape survivors, you may struggle with PTSD , anxiety , and depression. Your feelings of helplessness, shame, defectiveness, and self-blame are symptoms, not reality. No matter how difficult it may seem, with these tips and techniques, you can come to terms with what happened, regain your sense of safety and trust, and learn to heal and move on with your life.
Dispelling the toxic, victim-blaming myths about sexual violence can help you start the healing process. Many appear completely normal, friendly, charming, and non-threatening.

While working as an engineer for the Edison Illuminating Company in Detroit, Henry Ford built his first gasoline-powered horseless carriage, the Quadricycle, in the shed behind his home. In , he established the Ford Motor Company, and five years later the company rolled out the first Model T. Enormously influential in the industrial world, Ford was also outspoken in the political realm.
Ford drew controversy for his pacifist stance during the early years of World War I and earned widespread criticism for his anti-Semitic views and writings. At 16, he left home for the nearby city of Detroit, where he found apprentice work as a machinist. He returned to Dearborn and work on the family farm after three years, but continued to operate and service steam engines and work occasional stints in Detroit factories. In , he married Clara Bryant, who had grown up on a nearby farm.
In the first several years of their marriage, Ford supported himself and his new wife by running a sawmill. In , he returned with Clara to Detroit, where he was hired as an engineer for the Edison Illuminating Company. Rising quickly through the ranks, he was promoted to chief engineer two years later. On call 24 hours a day for his job at Edison, Ford spent his irregular hours on his efforts to build a gasoline-powered horseless carriage, or automobile.
Determined to improve upon his prototype, Ford sold the Quadricycle in order to continue building other vehicles. He received backing from various investors over the next seven years, some of whom formed the Detroit Automobile Company later the Henry Ford Company in After his departure, it was reorganized as the Cadillac Motor Car Company.

Thermoluminescence dating TL is the determination, by means of measuring the accumulated radiation dose, of the time elapsed since material containing crystalline minerals was either heated lava , ceramics or exposed to sunlight sediments. As a crystalline material is heated during measurements, the process of thermoluminescence starts. Thermoluminescence emits a weak light signal that is proportional to the radiation dose absorbed by the material.

A compound light microscope is a microscope with more than one lens and its own light source. In this type of microscope, there are ocular lenses in the binocular eyepieces and objective lenses in a rotating nosepiece closer to the specimen. Although sometimes found as monocular with one ocular lens, the compound binocular microscope is more commonly used today. The first light microscope dates back to , when Zacharias Jansen created a compound microscope that used collapsing tubes and produced magnifications up to 9X.
Microscopes have come a long way since then—today’s strongest compound microscopes have magnifying powers of 1, to 2,X. Because it contains its own light source in its base, a compound light microscope is also considered a bright field microscope.

New work shows how using next-generation DNA sequencing on ancient packrat middens — nests made out of plant material, fragments of insects, bones, fecal matter, and urine — could provide ecological snapshots of Earth’s past. Published today in the journal Ecology and Evolution , the study may pave the way for scientists to better understand how plant communities — and possibly animals, bacteria, and fungi as well — will respond to human-caused climate change.

Dating Techniques: Illuminating the past. May 05, A recent article in Nature discusses the impact of David Huntley (Professor Emeritus) and colleagues’.
While vertical erosion into bedrock landscapes has been extensively studied, there is little consensus on how rivers erode laterally in bedrock landscapes. It is crucial to establish the duration of lateral widening intervals that create bedrock valleys in order to understand how changes in river dynamics shape the Earth’s surface. Through a collaboration with the Desert Research Institute DRI , the PI will learn luminescence dating techniques that will allow her to establish the timing of lateral erosion intervals and apply these techniques to infer transport history of sediments.
Determining the timing of past and current river incision is important for predicting the effect of ongoing landscape change on humans who live and work near rivers in Kansas, the PI’s home state. The PI’s home institution, Kansas State University, will benefit from the professional development of the PI, her extended collaborative network with DRI, and the incorporation of dating techniques in research and teaching to demonstrate how local rivers change on decadal and centennial time scales that humans must be prepared to adapt to.
Technical Description The processes that control vertical incision in bedrock rivers are widely studied and well characterized; however, the fundamental processes that control lateral erosion have not been quantified in the laboratory or in the field. Field data that describes past channel mobility and defines absolute time constraints on the length of lateral erosion intervals are vital for better understanding the conditions that result in wide bedrock valleys.
Analysis of luminescence properties is a key tool for dating fluvial deposits to determine periods of lateral erosion and vertical incision. It also has the potential to illuminate transport processes, such as channel mobility, during periods of sediment deposition. Research conducted during this project has the potential to transform our understanding about the processes and timing of the evolution of bedrock valley systems.

Radiometric dating methods. The general principle of isotope dating methods is based on the presence of radioactive isotopes in the geologic or archaeological object to be dated. The decay with time of these isotopes is used to determine the ‘zero’ time corresponding to the event to be dated. Finally, the methods based on irradiation damages thermoluminescence, fission tracks, electron spin resonance are briefly evoked.

While the light microscope offers biologists the advantage in vivo imaging, it suffers from a reduced resolution due to constraints imposed in the optical domain. The hard limit on resolving power, known as the diffraction limit of resolution, is the distance of roughly one-half wavelength of the excitation light of an imaging system. Super-resolution imaging can relax the constraint on resolution.
Further constraints on resolving power are imposed by light wavefront aberrations. Sample-induced aberrations are inherent to biological samples. Other aberrations come from the microscope system itself. The canonical solution for wavefront aberration in a microscope is known as adaptive optics AO. Structured Illumination Microscopy SIM is an optical transfer function-based super-resolution technique that increases the support region in Fourier space via spatial frequency mixing.
In particular, the optical imaging system that acts as a low-pass filter on the image of the biological sample, favors low spatial frequencies. By optically mixing the biological sample with SIM fringes, high spatial frequency information from the sample is mixed into the pass band of the microscope. The results of this microscope are presented.

Rock-walled archaeological features are notoriously hard to date, largely because of the absence of suitable organic material for radiocarbon dating. This study demonstrates the efficacy of dating clam garden wall construction using optical dating, and uses optical ages to determine how sedimentation rates in the intertidal zone are affected by clam garden construction.
Clam gardens are rock-walled, intertidal terraces that were constructed and maintained by coastal First Nation peoples to increase bivalve habitat and productivity. These features are evidence of ancient shellfish mariculture on the Pacific Northwest and, based on radiocarbon dating, date to at least the late Holocene. Optical dating exploits the luminescence signals of quartz or feldspar minerals to determine the last time the minerals were exposed to sunlight i.
Optical ages were obtained from three clam garden sites on northern Quadra Island, British Columbia, and their reliability was assessed by comparing them to radiocarbon ages derived from shells underneath the clam garden walls, as well as below the terrace sediments.
